New CCD Digital Imaging Sensor is One of First with Full Resolution (1K x 1K) and High-speed Video (30 frames per second)
DALLAS (Sept. 15, 1997) -- With a new CCD (charge couple device) digital
image sensor from Texas Instruments, designers of demanding imaging systems, such as machine vision and medical imaging applications, can feature full-speed video (30 frames per second) and high resolution (1K x 1K pixels).
The new device, which is designated the TC281, is a progressive scan CCD
digital imaging sensor. It features low-smear imaging qualities because of
its high-speed parallel transfer architecture. The floating-gate technology incorporated in the TC281 gives it a low 10-to-20 electron noise floor at frequencies as high as 40 MHz. The TC281 produces an eight-micron square pixel and the device's advanced virtual phase technology simplifies system design because fewer clock signals are required to operate the sensor.
"Until now, designers of imaging systems had to settle for less than ideal
performance when it came to resolution and speed," said Dan Harmon, TI's
marketing manager for digital imaging sensor products. "The TC281 is one of the few CCD digital imaging sensors available today that doesn't sacrifice resolution for speed, or vice versa. Machine vision or medical imaging systems that combine both high resolution and full-speed video will have competitive advantage in the marketplace. The way to achieve this kind of end-equipment performance is to use a digital imaging sensor with the capabilities of the TC281."

Pricing and Availability
Engineering samples of the TC281 are scheduled to be available during the
first quarter of 1998 with production volumes available during the second
quarter. Suggested resale pricing in quantities of 1,000 is $825.
